Cooperative Resource Sharing Between Agents in Multi-Distributed Fog Nodes

Cloud computing provides high computation resources to the user's applications. Some of the user's applications are time-sensitive. Therefore, processing these applications in traditional cloud computing centers might fail due to the high latency between the cloud layer and the user equipment layer. Thus, to solve this issue, fog computing is deployed near the user's nodes layer to extend the cloud layer and provide computation resources with low latency. The fog computing layer may contain limited devices compared to the cloud layer. As a result at peak hours, when multiple tasks are requested from IoT applications to the fog nodes, communication congestion might occur and the processing time will significantly increase. In addition, the fog layer may contain limited resources and limited power, and many of the requested tasks will be offloaded to the cloud layer for processing. Consequently, the purpose of the fog layer is not accomplished. In this paper, we propose a cooperation scheme between fog nodes to process tasks requested from IoT nodes with minimum service latency and maximum throughput.
